Scissors, Surgical, Eye, Extraocular Muscle/Strabismus
Definition : Eye (ophthalmic) surgery scissors designed to cut the extraocular muscles during ophthalmic procedures, usually in surgery to correct strabismus. These scissors are typically very small handheld, manual instruments with two metallic (e.g., stainless steel) blades with straight or slightly curved sharp tips that slide past each other (i.e., shearing action). The blades are attached to handles with the proximal end conformed as a ring to facilitate holding and operating with the fingers and are joined by a swivel pin in the center; scissors with larger finger rings and flat shanks to facilitate operation (e.g., ribbon style) are also available. Extraocular muscle/strabismus scissors are used to cut one or more of the six extraocular muscles that provide motility to the eye, either in muscle recession or resection procedures intended to improve the alignment of the eyes (i.e., correct strabismus).
